V Specification of Letters Patent Patented Blay 13, 1919,

Application filed November 24, 1917.. Serial No. 203,742.

provide a burner of this character so 0011- structed that a light may beused in connection therewith and yet occupy a minimum amount of space,one coupling operating to effect a connection with the supply pipeofboth the stove burner and that for supply ing light. i

rinother object is to provide an improved form of stove burner whereby amaximum amount of heat may be obtained with aminimum consumption of gasand inwhichthe heating area is largely increased without increasing theconsumption of gas.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodimentof the invention herein disclosed may be made within the scopeof what is claimed with out departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a top plan view of aburner constructed in accordance with this invention, and

Fig. 2 represents a transverse vertical section thereof.

In the embodiment illustrated a burner is shown adapted for connectionwith any suitable source of gas supply, a pipe 1 being here shownprovided with an annular flange or shoulder 2 on which the burner isdesigned to be supported.

The burner constituting this invention comprises a substantiallyfrusto-conical 'hollow gas tube 10 having means at its lower end forsupporting it on the pipe 1 in a manner hereinafter to be described.This frusto-conical casing carries at its upper end the burner proper 11which is here shown in the form of a circular casing including a top 12and bottom 13 spaced a suitable distance from each other to form a gasreceiving chamber, the gas being directed tllBlQll'ltO from the tubelOas is shown clearly in Fig. 2. The bottom 13 may be secured to the upperend of the tube 10 in any suitable manner, being here shown crimped inengagement therewith and an opening 14 is provided in one side wall ofthe burner casing for a purpose presently to be described.

Arranged around the topor upper face .12 of the. burner adjacent theperimeter thereof is a plurality of spaced gas discharge apertures 15which may bedisposed at any suitable distance from each other in amanner common With burners of this character. ()pening through thecasing 11 are a plurality of air drum tubes 16, five being here shownarranged in a circle, although obviously they may be disposed in anyother desired manner. Around the upper end of each of these tubes 16 area plurality of gas discharge apertures 17, the gas passing therethroughbeing mixed with air admitted through the lower ends of the tubes sothat a mixture is provided which will result in maximum amount of heatbeing produced with a minimum consumption of gas.

A. gas pipe .3 extends upwardly through the tubular member 10 and has anelbow coupling 4: at its upper end which connects an arm 5 therewith,said arm extending radially through the casing 11 and out through theopening 14: thereof where it is provided with a gas jet6, the supply ofgas to said jet being controlled by the usual valve or cock 7 This gasjet may be disposed at any suitable or desired distance relatively totheburner casing 11, the object being to supply light to said burner duringthe cooking operation. 1 A branch pipe 8 leads from the pipe 3, beingconnected therewith by a T-coupling 9 andis provided with a dischargenozzle 18 controlled by the usual valve 19 having an actuating handle 20extending through the side wall of the tubular member 10 so that the gaspassing through said pipe 8 may be turned on or cut 05 at the will ofthe operator. It is understood that the gas to the burner casing 11 issupplied through this branch pipe 8 and it will thus be obvious that theburner may be supplied with gas independently of the gas jet 6 and viceversa. By so positioning the gas supply pipe 3 which supplies both theburner and the gas nected with any other pipe at any point'desired.

The depending frusto conical tube has an outwardly projecting annularflange 21 at its lower end around which is crimped an apertured plate 22and an outer aperturecl plate 23 isarranged over said plate 22 andadapted to turn thereon for controlling theamount of air admitted to thecasing.

It will thus beseen that the head plate 01' crown of the burner which isformedby the top 12 of the casing 11 will, when constructed as abovedescribed, emit a great number ofsmall jets of gas which mingle with theair passing upward through the tube 16.

and thus produce a maximum heating efi'ect and this plate when soconstructed, presents a large heating area so that large vessels may beused in connection therewith as well as small ones;

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethodof operation will be readily apparent to those skilled in the artto which the invention appertains and while I have described-theprinciple of operation of the inventiontogether with the device which Inow consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that suchchanges may be made as are within the scope of the claimed invention.

' I claim '1. A hollow stove burner having a depending casingcommunicating therewith, a gas supply pipeextending through said casingand projecting through one side wall of the burner, a gas jet mounted onsaid projecting pipe end, and a valve controlled branch pipe openinginto said casing. for supplying gas to the burner.

A hollow stove burner having a dependingcasing communicating therewith,a gas supply pipe extending through said casing and 'projecting'throughone side wall of the burnerfa gas jet mounted on said projecting pipeend, and a valve controlled branch pipe opening into said casing forsupplying gas to the burner, said burner having a plurality of tubesopening vertically therethrough with discharge openings at 'their upperends for the passage of gas,

air being admitted through the bottom of said tubes.

3. A burner comprising a hollow casing having apertures for the passageof gas therefrom, and provided with a depending tubular membercommunicating therewith, a gas pipe extending through said tubularmember and through said casing with a gas jet therein outside saidcasing, a valve con trolled branch pipe opening into said tubular memberfor supplying gas to the burner, valve controlled means for supplyingair to said tubular member, and a control valve for said gas jet.

4. A stove burner comprising a circular casing having 'a plurality ofgas discharge apertures arranged around its upper face adjacent itsperimeter, a plurality of tubes extending vertically through said casingand having openings around their upper ends communicating with theinterior of the easing, and means for supplying gas to said casing.

5. A stove burner comprising a circular casing having a plurality of gasdischarge apertures arranged around its upper face adjacent itsperimeter, a plurality of tubes extending vertically through said casingand having openings around their upper ends communicating with theinterior of the casing, a tubular member depending from said casing, agas pipe extending up through said tubular member and when laterallythrough said casing projecting beyond the outer facethereof, a valvecontrolled gas jet carried by said projecting pipeend adjacent thecasing to provide light for the burner, and a valve controlled branchpipe opening into said depending tubular memher for supplying gas to thecasing.

In testimony whereof I aflix my signature in presence of two witnesses.
